I have had my Airlift airbags for almost two years. The compressor comes on every time I start the truck and then about every 5 minutes after that. I have had it back to the shop that installed it four times to check for leaks. They swear there are no leaks I called Airlift last year and they sent me an inline check valve which the shop installed. That did nothing. I just called Airlift again and they told me that there has to be a leak somewhere in the system. It only seems to do this when I have my camper on the truck. I am at my wit's end. I am about ready to yank everything out and put a Firestone system on. I had Firestone on my last truck and never had any problems. Has anybody else had a problem with Airlift? Any advice?
